Publication number: 20240083024Abstract: A spring constant correction device and method measure a position and attitude of a distal end of an articulated robot when the articulated robot is operated in a state where elastic deformation is compensated, compare measurement values of the position and attitude of the distal end and target values of the position and attitude, and correct a spring constant based on a result of the comparison. In case of the correction, the spring constant is corrected at a predetermined position based on at least three of: an angle of an end point attitude based on the measured attitude; a torque of the distal end in the end point attitude; an angle of the distal end in a target attitude; and a torque of the distal end in the target attitude. A program of such a method is recorded in a recording medium.Type: ApplicationFiled: January 13, 2022Publication date: March 14, 2024Applicant: Kabushiki Kaisha Kobe Seiko Sho (Kobe Steel, Ltd.)Inventors: Takashi YAMADA, Yoshiharu NISHIDA, Yoshihisa TAMASE, Naoki KIDA, Kenichiro KANAO

Patent number: 10737346Abstract: Provided is a welding robot mechanism that has: a welding robot having a touch sensing function; a welding power source for supplying welding power to the welding robot; and a control unit for controlling the welding robot, wherein the welding power source has a welding power source communication unit that receives detection signals with regard to control of the welding robot and the touch sensing, and transmits the detection signals outward. The control unit is linked to the welding power source communication unit via a serial bus communication wire. The detection signals comprise a mass of data including a detection data group designated as a first group and a detection data group designated as a second group, and is configured to read the detection data group designated as the first group in a shorter cycle than that for the detection data group designated as the second group. The detection data group designated as the first group includes a detection signal obtained by the touch sensing.Type: GrantFiled: February 8, 2017Date of Patent: August 11, 2020Assignee: Kobe Steel, Ltd.Inventors: Tsutomu One, Takashi Wada, Shuichi Inada, Atsushi Fukunaga, Naoki Kida
